Description

Technical Field

[0001] The invention relates to the field of sanitary ware, in particular to a nozzle and a spray rod, a spray washing device and a method for separating a buttock washing hole from a feminine washing hole. Background Art

[0002] Many smart toilets in the prior art are generally equipped with a spray device for cleaning the private parts of the human body. The core component of this spray device is a spray rod, and the front end of the spray rod is a nozzle. The nozzle is usually provided with a buttocks washing hole and a women's washing hole, which are respectively used to achieve buttocks washing and women's washing. Since the buttocks washing hole and the women's washing hole are located on the same nozzle, this nozzle has the hidden danger of cross infection (when performing buttocks washing, if dirt falls on the nozzle, it is easy to contaminate the women's washing hole, resulting in the women's washing area being easily infected by bacteria and viruses carried by the dirt during women's washing). For this reason, some spray devices are provided with two spray rods arranged side by side on the left and right, and the nozzles of the two spray rods are used to achieve buttocks washing and women's washing respectively. This spray device certainly solves the problem of cross infection, but due to the provision of two spray rods, the overall volume is larger, the structure is more complex, and the cost is higher.

[0044] For examples, see Figure 1-11 As shown, a nozzle of the present invention includes a nozzle body 1, which is provided with a posterior wash hole that can discharge water upward or at an angle upward, and a posterior wash water channel connected to the posterior wash hole; and a small hygienic spray boom 2, which is provided with a hygienic spray hole 211 that can discharge water upward or at an angle upward. The small hygienic spray boom 2 is telescopically disposed within the nozzle body 1. When the small hygienic spray boom 2 is extended, the hygienic spray hole 211 is exposed; when the small hygienic spray boom 2 is retracted, the hygienic spray hole 211 is concealed within the nozzle body 1. The hygienic spray hole 211 is specifically disposed at the front end of the small hygienic spray boom 2. The front end of the small hygienic spray boom 2 refers to the portion exposed outside the nozzle body 1 when the small hygienic spray boom 2 is extended. The front and back are defined as follows: the direction in which the small hygienic spray boom 2 is extended toward the person is the front, and the direction in which the small hygienic spray boom 2 is extended toward the person is the back.

[0045] In this embodiment, during washing, the small washing boom 2 is propelled by water to extend the portion containing the washing hole 211. When washing stops, the small washing boom 2 is retracted by a preset reset component. In this embodiment, the nozzle body 1 is further provided with a washing water channel 112 connected to the washing hole 211. When water flows into the washing water channel 112, the small washing boom 2 is propelled by water to extend the portion containing the washing hole 211 (i.e., the front end of the small washing boom 2). Water enters the small washing boom 2 and is sprayed out of the washing hole 211. When water stops flowing into the washing water channel 112, the small washing boom 2 is retracted by a preset reset component. Therefore, the small washing boom 2 is extended by water and retracted by a reset component, eliminating the need for manpower and electricity, making it more convenient and energy-efficient. In other embodiments, the small spray boom for women's washing is extended and retracted by manual pulling and pushing, or the small spray boom for women's washing is extended and retracted by an electric drive mechanism, which can be, for example, a motor and a gear transmission assembly.

[0046] In this embodiment, the small washing spray bar 2 is also provided with a negative pressure suction structure, so that the washing hole 211 can spray out bubble water mixed with water and gas. Figure 3As shown, the negative pressure suction structure includes an air intake hole 212 and an acceleration hole 214. The acceleration hole 214 is located within the small washing boom 2 and divides its internal flow path into a front flow path 213 and a rear flow path 215, which are arranged from front to back. The front flow path 213 connects to the rear flow path 215 through the acceleration hole 214. The air intake hole 212 and the washing hole 211 are located on the same side of the small washing boom 2, with the air intake hole 212 located behind the washing hole 211. After water enters the rear flow path 215 of the small washing boom 2, it is accelerated through the acceleration hole 214 and enters the front flow path 213, generating negative pressure in the front flow path 213 and drawing air in through the air intake hole 212. The aperture D1 of the washing hole 211 is larger than the aperture D3 of the acceleration hole 214, while the aperture D2 of the air intake hole 212 is smaller than or equal to the aperture D3 of the acceleration hole 214.

[0047] In this embodiment, the inner wall of the front flow channel 213 is provided with a rectifying slope 216 located behind and adjacent to the wash hole 211. The angle β between the rectifying slope 216 and the wall on which it is located is an obtuse angle. The rectifying slope 216 guides and rectifyes the water flow, ensuring a stable flow exiting the wash hole 211.

[0048] In this embodiment, the reset component is a spring 3, which is mounted outside the small washing spray boom 2, with its rear end abutting against the annular boss 217 provided at the rear end of the small washing spray boom 2, and its front end abutting against the front of the nozzle body 1. In other embodiments, the reset component is a first magnet, with opposite poles of the first magnet and the second magnet provided on the nozzle body. Therefore, when water stops flowing into the washing water channel, the small washing spray boom retracts backward due to the magnetic attraction between the first and second magnets. In other embodiments, the reset component includes the spring and the first magnet. In this way, when water stops flowing into the washing water channel, the small washing spray boom retracts backward due to the restoring force of the spring and the magnetic attraction between the first and second magnets.

[0049] In this embodiment, a sealing ring 4 is provided at the rear end of the small washing spray boom 2. When the small washing spray boom 2 is extended, the sealing ring 4 seals the gap between the small washing spray boom 2 and the nozzle body 1. Specifically, the nozzle body 1 is provided with an annular water stop 114 at the front end of the washing water channel 112. When the small washing spray boom 2 is extended forward, the sealing ring 4 abuts against one side of the annular water stop 114, thereby achieving a water-stopping effect. The rear end of the small washing spray boom 2 is provided with an outer flange 218. The outer diameter of the outer flange 218 is slightly smaller than the inner diameter of the washing water channel 112. This ensures smooth extension and retraction of the small washing spray boom 2 while reducing pressure release caused by water overflowing from the gap between the small washing spray boom 2 and the washing water channel 112, ensuring that the water entering the washing water channel 112 has sufficient pressure to propel the small washing spray boom 2 out.

[0050] In this embodiment, the nozzle body 1 and the small washing spray boom 2 are equipped with a limiting structure for limiting the telescopic stroke of the small washing spray boom 2. The limiting structure includes a long strip limiting slide 221 provided along the front-to-back direction on the outside of the small washing spray boom 2 and a limiting protrusion 131 provided on the nozzle body 1. The limiting slide 221 is slidably engaged with the limiting protrusion 131.

[0051] In this embodiment, there are a plurality of hip wash holes, and the spraying strength of the plurality of hip wash holes is different. There are a plurality of hip wash water channels, and the plurality of hip wash water channels are connected to the plurality of hip wash holes in a one-to-one correspondence. Specifically, there are two hip wash holes. For the sake of convenience, the two hip wash holes are named as the strong wash hole 122 and the soft wash hole 121, respectively. The strong wash hole 122 is located behind the soft wash hole 121. There are two hip wash water channels. For the sake of convenience, the two hip wash water channels are named as the soft wash water channel 111 corresponding to the soft wash hole 121 and the strong wash water channel 113 corresponding to the strong wash hole 122. The spraying force of the strong wash hole 122 is greater than that of the soft wash hole 121. Specifically, the strong wash water channel corresponding to the strong wash hole 122 has no suction effect, so that the water column coming out of the strong wash hole 122 is in the shape of a small column with strong force. The soft wash water channel 111 corresponding to the soft wash hole 121 has a suction effect, and the air suction is relatively large, so that the water splashes coming out of the soft wash hole 121 are in the shape of bubbles with weakened force.

[0052] In this embodiment, the nozzle body 1 includes a nozzle body 11, a nozzle upper cover 12 and a nozzle lower cover 13. The nozzle upper cover 12 is provided with the soft wash hole 121 and the strong wash hole 122 and is sealed with the nozzle body 11. The nozzle body 11 is provided with the hip wash water channel and the feminine wash water channel 112. Specifically, Figure 5 As shown, the bottom of the nozzle cover 12 is provided with several welded ribs 123, which are ultrasonically welded to the nozzle body 11. A circular panel 124 is provided at the front end of the nozzle cover 12, located in front of the nozzle body 11. This circular panel 124 has a through hole 125 through which the front end of the small washing lance 2 passes. This through hole 125 is a flat hole, and the small washing lance 2 is a flat rod. The two holes 125 and 125 are aligned to prevent the small washing lance 2 from rotating relative to the nozzle body 1. The nozzle lower cover 13 is snap-connected to the bottom of the nozzle body 11. Specifically, the nozzle lower cover 13 is provided with two snaps 132, which snap into place with the two snap holes 115 provided on the nozzle body 11. The small washing lance 2 is located between the nozzle lower cover 13 and the nozzle body 11. A stopper 131 is provided on the nozzle lower cover 13. The front portion of the nozzle body 11 is provided with two limiting ribs 116 distributed on the left and right sides, and the front end of the spring 3 abuts against the two limiting ribs 116 .

[0053] In this embodiment, the small spray boom 2 for women's washing includes a main boom body 21 and a lower boom cover 22. The main boom body 21 is provided with the aforementioned women's washing hole 211, the air intake hole 212, the acceleration hole 214, and the rear flow channel 215. The lower boom cover 22 is sealed to the lower portion of the main boom body 21 by ultrasonic welding, and the two together form the aforementioned front flow channel 213. The limiting slide 221 is provided at the bottom of the lower boom cover 22.

[0054] When assembling a nozzle of the present invention, first, the small spray bar 2 for washing women is installed through the water channel 112 of the nozzle body 11, and the front end of the small spray bar 2 is inserted into the through hole 125 of the front panel 124 of the nozzle upper cover 12; then, the nozzle lower cover 13 is buckled on, so that the limiting protrusion 131 on the nozzle lower cover 13 corresponds to the limiting groove 221 at the bottom of the small spray bar 2.

[0055] The nozzle of the present invention is installed at the front end of the spray rod body of the spray washing device when it is used, and as a preferred embodiment, the nozzle is set to be detachable so that the nozzle can be replaced and cleaned. The nozzle of the present invention can be divided into two states according to whether its small spray rod 2 of the washing machine is extended or not. The first state is as follows: Figure 6-Figure 8 As shown, at this time, the women's wash water channel 112 has no water, and the women's wash small spray rod 2 is retracted into the nozzle body 1. In this state, if the soft wash water channel 111 or the strong wash water channel 113 has water, the water will be sprayed out from the soft wash hole 121 or the strong wash hole 122 to achieve the buttocks washing function. Figures 9-11 As shown, at this time, if water enters the wash water channel 112, the water flow pushes the small wash spray bar 2 forward, overcoming the elastic force of the spring 3, exposing the wash hole 211. When the sealing ring 4 on the small wash spray bar 2 contacts the annular water stop 114 in the nozzle body 11, the small wash spray bar 2 stops extending forward. Water in the wash water channel 112 enters the small wash spray bar 2 and is ejected from the wash hole 211 thereon, achieving the wash function. Because the small wash spray bar 2 is also provided with the suction hole 212 and the acceleration hole 214, the small wash spray bar 2 can generate a self-aspiration effect, sucking in external air through the suction hole 212 and mixing it with water to form bubble water. This bubble water is rectified by the rectifying slope 216 and stably ejected from the wash hole 211. When water stops entering the wash water channel 112, the spring 3 returns to its original position, forcing the small wash spray bar 2 to retract, concealing the wash hole 211 within the nozzle body 1.

[0056] The nozzle of the present invention also includes the small spray bar 2 for women's washing. When women are washing, the small spray bar 2 for women's washing is extended. When women are not washing, the small spray bar 2 for women's washing is retracted. Therefore, when the nozzle is used to wash the buttocks, the women's washing hole can be prevented from being exposed and dirt can fall in, thereby avoiding cross infection. At the same time, the present invention solves the problem of cross infection without the need to set up double spray bars in the spraying device, thereby making the spraying device simpler in structure, lower in cost, smaller in size, and meeting the requirements of the nozzle being removable and cleanable. In addition, the small spray bar 2 for women's washing is extended and retracted by water pressure and reset components, without the need for electricity, and is more energy-efficient.

[0057] See Figure 12-15 As shown, a spray rod of the present invention includes a spray rod body 5 and a nozzle as described in the present invention above. The nozzle is arranged at the front end of the spray rod body 5, and the spray rod body 5 is provided with a plurality of water outlet channels corresponding to the buttock washing hole and the women's washing hole (specifically, the buttock washing water channel and the women's washing water channel).

[0058] In this embodiment, the nozzle is detachably connected to the spray rod body 5, but the present invention is not limited thereto.

[0059] In this embodiment, the spray boom of the present invention further includes a waterway switching mechanism that controls whether each outlet waterway discharges water. The waterway switching mechanism specifically includes a waterway switching slider 6 and a first drive mechanism 7. The waterway switching slider 6 is provided with an inlet waterway. The waterway switching slider 6 is slidably connected to the spray boom body 5 and driven by the first drive mechanism 7 disposed on the spray boom body 5, so that the inlet waterway switches into communication with at least the plurality of outlet waterways.

[0060] In this embodiment, the boom body 5 specifically includes a boom upper shell 51 and a boom lower shell 52, which are sealed together by ultrasonic welding to form the plurality of water outlet waterways. The waterway switching slider 6 is specifically slidably connected to the boom upper shell 51. The first drive mechanism 7 specifically includes a first motor 71 and a switching gear 72. The first motor 71 is disposed at the rear end of the boom lower shell 52. The switching gear 72 is disposed on the output shaft of the first motor 71 and meshes with the first rack 61 provided on the waterway switching slider 6.

[0061] In this embodiment, the spray boom of the present invention further includes an outer sleeve 8 made of stainless steel, which is sleeved outside the spray boom body 5 and is provided with two small holes 81 for avoiding the soft wash hole 121 and the strong wash hole 122. The spray boom body 5 is also provided with a self-cleaning water channel and a self-cleaning water nozzle 9. The self-cleaning water nozzle 9 is connected to the self-cleaning water channel, and the self-cleaning water channel is controlled by the water channel switching slider 6. Specifically, the water channel switching slider 6 is driven by the first drive mechanism 7 to switch the water inlet water channel with the plurality of water outlet water channels and the self-cleaning water channel.

[0062] The spray rod of the present invention adopts the nozzle, and its overall structure is relatively simple. When the woman is washing, the small spray rod 2 of the woman is extended, and when the woman is not washing, the small spray rod 2 of the woman is retracted. Therefore, when the nozzle is used to wash the buttocks, the woman's washing hole is prevented from being exposed and dirty, thereby avoiding cross infection.

[0063] A spray cleaning device of the present invention includes a fixed body, a second driving mechanism, and also includes the spray rod as described above in the present invention. The spray rod body 5 can be telescopically arranged on the fixed body and driven by the second driving mechanism.

[0064] In this embodiment, the second driving mechanism specifically includes a second motor and a gear transmission assembly. The second motor is arranged on the fixed body and is connected to the second rack 521 provided on the spray rod body 5 (specifically the spray rod lower shell 52) through the gear transmission assembly.

[0065] A spray washing device of the present invention realizes spray washing. When the second motor is started, it drives the spray rod body 5 to extend. At this time, if water enters the soft washing water path 111 of the nozzle body 1, the buttocks washing function is realized. If water enters the feminine washing water path 112 of the nozzle body 1, the feminine washing small spray rod 2 is extended to realize the feminine washing function.

[0066] The present invention provides a method for separating a breechwash hole from a feminine wash hole. The method comprises providing a breechwash hole and a small, retractable feminine wash boom on a spray boom or its nozzle. The small feminine wash boom is provided with a feminine wash hole. When the small feminine wash boom is extended, the feminine wash hole is exposed. When the small feminine wash boom is retracted, the feminine wash hole is concealed. Specifically, the small feminine wash boom is retractably provided on the nozzle of the spray boom. When the small feminine wash boom is retracted, the feminine wash hole is concealed within the nozzle.

[0067] In this embodiment, during washing, the small washing boom is propelled by water to extend the portion containing the washing hole. When washing stops, the small washing boom is retracted by a preset reset component. Specifically, the small washing boom is propelled by water entering the nozzle and used for washing to extend the portion containing the washing hole. When water entering the nozzle for washing stops, the small washing boom is retracted by a preset reset component. The reset component is specifically, but not limited to, a spring. In other embodiments, the small washing boom is extended and retracted by manual pulling or pushing, or by an electric drive mechanism, such as a motor and a gear transmission assembly.

[0068] In this embodiment, the small washing spray bar is further provided with a negative pressure suction structure, so that the washing hole can spray out bubble water mixed with water vapor.

[0069] The present invention provides a method for separating the breechwashing hole from the feminine wash hole. When the nozzle is used for breechwashing, the feminine wash hole is prevented from being exposed and contaminated, thereby preventing cross-contamination. Furthermore, the present invention eliminates the need for a dual-spray spray device to address the cross-contamination issue. This makes the spray device simpler, less expensive, and smaller in size, while also meeting the requirements for a removable and cleanable nozzle.

[0070] The method of the present invention for separating the buttocks washing hole from the feminine washing hole can be realized by using the nozzle, spray rod and spray washing device of the present invention.

[0071] The nozzle and spray rod, spray washing device and method for separating the buttock washing hole and the feminine washing hole of the present invention, the unrelated parts are the same as those in the prior art or can be implemented by using the prior art.

[0072] The above embodiments are only used to further illustrate a nozzle and spray rod, a spray washing device and a method for separating the buttock washing hole and the feminine washing hole of the present invention, but the present invention is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention fall within the scope of protection of the technical solution of the present invention.
